ZL30100QDG1

ZL30100QDG1 is an evaluation/development kit for the ZL30100 timing/clock-management device (originally from Zarlink, now Broadcom). It ships as a ready-made PCB (QDG1) that includes the ZL30100 silicon, a USB/JTAG interface, power, and test/connectors. The kit lets you configure ZL30100 registers, route clock/data paths, and test jitter-cleaning and PLL functions through a PC GUI provided by the vendor. It targets telecom and data-communications timing applications such as clock distribution and high-speed SERDES interfaces. Typical workflow: install drivers, connect via USB, run the GUI, select a reference clock, load an example configuration, and run measurements with built-in test patterns. Documentation usually includes a user guide and datasheet with pinout, electrical specs, and application notes. If you need exact current specs or the precise vendor name, please share a link or datasheet and I’ll summarize the features.

- Pin count: 16 pins (QFN package, ZL30100QDG1)
